a motor floor construction of suchform the fiooror roof reinforcing members are initially assembled on boards which eventually become the ceiling facingand the rein- "iorcing members become incorporated in the moldable material after the latterv has set; and to provide a construction which will. reduce thenumberof steps, as wellas the inaterial required; in building, so that a material saving in cost will result thereby. With this object in v ew, the invention consists in construction and combination of parts of which'preferred embod ments,

As illustrated in the accompanying drawings the roof consists of sections 1 of ,fireproof material the adjacent sections having abutting edges whereby the sections-lie in. a common plane; In the roof structure rails 2 are laid upon the sections 1 in parallel-relation and the said rails are preferably plan viewot a modified formed from sheet'metal as indicated in i F igure 30f the drawing the said'rails havv ing-outstanding base 'flanges3 and substantially cylindrical head portions 4 connected with the flanges.- by web..p0rtions 5.'*-'' As shoWninFigures'Q and dot the drawings clinching devices which penetrate the sectionsl and "have their ends clinched over the upper surfaces. of the base iflanges 3 ofthe rails; As shown in Figure 11 of the drawings the clinching devices consist of yokes '7v which pass over the heads of the rails 4 and the side portions of the said .yokes penetrate the sections 1 and the tree end ar the side are clinchedagainst the under surfacesof the sections 1. v

The rails 2are also in" sections and these sections align longitudinally with each other asbest shown in Figure 6 of the drawings. The web portions of the ad acent railsections are providedwith' openings 8 and plates 9 extend-over the heads of the adja-' cent ends of the rail sectionsand the said plates 9 areprovidedwith tongues ,10Iwhich pass through the openings 8 and which are disposed against the sides of the webs of the adjacent section. Thus the rail sections bridging plate 11 which is disposed across the abutting edges of the adjacent roof sections as indicated in Figure 1 of the drawings. The plate 11 is provided at itsopposite edges with flange portions 12 which are disposed over the rear sections upon the adjacent roof section and the plate 11 is provided at its center with an opening 13 which 1" serves a bolt 14:. The boltv 1s disposed between the adjacent roof sections 1 as most clearly shown in Figure 8 of the drawings. The bolt 14 passes .through a clip; member 15 which is provided with a return end portion adapted to engage under the upper flange of a roof beam 16. The plate-11 is provided with strengthening, ribs 17 which are pressed therein and at its opp0- site edges the plate 11 is provided with upstanding flangcs 18 the said flanges being disposed acrossthe abutting edges of the adjacent roof sections 1. Plastic roof mate-- rial 19 of gypsum or other fireproof material is filled in between the rails 2 and the upper surface of the material 19 is troweled down to the level of several inches above the upper edges of the rail sections. A roof so constructed is of strong and durable nature and is fireproof.

In the form of rail as shown in Figures 12 to 15 inclusive the same is made with a head portion l whichis rectangular in cross-section. Otherwise this form is the same as that shown in Figures 1, 2' and 3.

The plate 20 is provided with a web portion 21 which fits against one side of the position and shape as shown in Figure web portions of the rails, and the portion 21 is extended into a flange 22 which rests upon the base flanges of the rails d. Rivets 23 pass transversely through the portion 21 and the webs of the rails l. The intermediate portion of the plate is bent down over the heads of the rails i, by the use of a special tool (not shown) so that it assumes the 15 and a flange 2% of the plate bears against the sides of the webs of the rails i. The edge of the flange 24 lies above the rivets 23. By such arrangement the plate may be ap plate fits snugly upon the rails just above the rivets. The rivets may be spot velded,

soldered or otherwise suitably secured in position.

The form of rail shown in Figure 17 consists of a strip of sheet metal folded upon itself to form a broad base flange 25. The web portions 26 extend up from the medial length of the base flange and the head flanges 27 are disposed parallel with the base flange. Said rail section may be formed by a rolling operation and the rail possesses great strength. g In the arrangement as shown in Figures 18, 19 and 20 the structure includes the rails having overlapping end portions, the said rails having their base flanges 25 located above the sections 1 and a pin 28 passes through the webportions of adjacent rails in the vi'cinty of the ends thereof. Clips 6 are carried by the base flanges of the rail and pass through the sections 1. A bar 29 rests upon the heads 27 of adjacent rails and a clip 30 is mounted .upon the bar 29 and.

passes between the sections 1 and the lower end of the clip 30 engages under the top flange of the beam 16, as best shown in Figure 20 of the drawings. This is a very strong structure and provides a positive an-' length suflicient to span adjacent beams set to support the ceiling or floor structure. These rails are assembled by being attached to the fireproof sections in parallel relation, preferably closely spaced. They thus serve to reinforce the sections and when the latter are laid on the supporting beams, the seams between adjacent sections running longitudinally of the beams are disposed over the top faces of the latter and the rails are arranged transversely of the beams. Thus the reinforced sections replace the false work customarily employed for receiving the molded floor or roof. The moldable material is thendeposited'on top of the sections and troweled or otherwise worked to 1 a level above the level of the upper edges of the rails, so that when set, the rails become incorporated with the molded material to serve as a metallic reinforcement for the same,-

while the sections to which the rails were initially attached constitute the ceiling-facing of the completed structure .and may be faced with a white coating of plaster or wit any other finishing means desired.

Having described the invention what is claimed is v r 1. In a structureas described sections of fireproof material having abutting edges, rails laid upon said sections in parallel rela tion, means for clinching the rails to the sections, a bridging plate disposed over the seam between the sections and provided at opposite edges with flanges disposed over the adjacent rails, said bridging plate having at its intervening edges upstanding flanges, and a plastic filler of fireproof material laid upon the sections between the rails and having an upper surface troweled to a level above the upper edges of the rails.
